MPG calculator

If, like me, you calculate your mpg by filling up, resetting the trip counter,
then drive a few hundred miles, fill up again, then spend hours trying to work
out how many litres you used, converting it into gallons, then working out
you MPG, then this calculator is for you. Just tell it how many miles you did,
how much it cost & what the price per litre was & it'll do it all for
you.

Ok, so now we know the on road MPG, so lets do a little
more maths. How much is this trip going to cost in fuel?
